DETAILED DESCRIPTION

In order to help those skilled in the art better understand solutions of the present disclosure, hereinafter technical solutions in embodiments of the present disclosure are described clearly and completely in conjunction with the drawings in embodiments of the present closure. Apparently, the described embodiments are only some rather than all of the embodiments of the present disclosure. Any other embodiments obtained based on the embodiments of the present disclosure by those skilled in the art without any creative effort fall within the scope of protection of the present disclosure.

A method for performing a test for a CPU is provided according to an embodiment of the present disclosure. Reference is made to FIG. 1, where the method includes steps S11 to S13.

In step S11, a SETWP test is executed for a CPU, a first command-executing duration corresponding to a decay command in the SETWP test is determined, and the first command-executing duration is deployed.

Reference is made to FIG. 2 for a specific embodiment. In a former half of the test, the commands for SVID Dn and SVID Up are both “Fast”. In such case, a corresponding waveform can be obtained when an official script is directly executed, and then corresponding data is measured.

In a latter half of the test, the command for SVID Dn changes from “Fast” to “Decay”, as shown in FIG. 3.

Reference is made to FIG. 4. Commands No. 1, 3, 4, 5, 6, 8, 9, and 10 need to be executed in the test. Commands No. 1, 3, 4, and 5 are for the former half of the test, while commands 6, 8, 9, and 10 are for the latter half of the test. Embodiments of the present disclosure focus mainly on the latter half of the test.

When the latter half of the test is executed, a value of SETWP date should be changed from 22 to 32, besides a command for the SVID Dn is changed from “Fast” to “Decay”, as shown in FIG. 4. Then, the commands No. 6, 8, 9, and 10 are executed.

After the commands No. 6, 8, 9, and 10 are executed for the first time, a result of executing the commands No. 8, 9, and 10 is “F”, meaning an error (“Fail”), as shown in the last column in FIG. 4. Then, the first command-executing duration corresponding to the decay command in the SETWP test is determined and deployed. The first command-executing duration is a value of “Delay” in row No. 6 in FIG. 4.

References are made to FIG. 5 and FIG. 6. An optional embodiment is based on this embodiment. A process of determining the first command-executing duration corresponding to the decay command in the SETWP test may include steps S21 to S23.

In step S21, a first moment at which the earliest rising edge appears in the generated cso signal and a second moment at which an earliest falling edge appears in the generated alert signal are acquired.

In a specific embodiment, the cso signal is a curve in an uppermost part of FIG. 6, and the alert signal is a curve in a middle part of FIG. 6. The first moment at which the earliest rising edge appears in the generated cso signal and the second moment at which the earliest falling edge appears in the generated alert signal are acquired.

In step S22, a first temporal difference between the first moment and the second moment is calculated.

In step S23, the first command-executing duration is calculated according to the first temporal difference.

A technician sets the first command-executing duration for executing the decay command.

An optional embodiment is based on this embodiment. The step S23 may include a following step.

A ratio of the first temporal difference to a preset value is calculated, and the ratio serves as the first command-executing duration.

In a specific embodiment, the preset value may be 40. That is, the first time command-executing duration is equal to the ratio of the first temporal difference to 40.

In step S12, the SETWP test is executed again, and a command-executing duration corresponding to each command subsequent to the decay command in the SETWP test is adjusted.

In a specific embodiment, after the first command-executing duration corresponding to the decay command is deployed, the SETWP test is executed again. Then, the command-executing duration corresponding to each command subsequent to the decay command in the SETWP test is adjusted in turn.

When the command-executing duration corresponding to each command subsequent to the decay command is deployed, the SETWP test can be normally executed, and the executing result of each command is “P”, which means passing (“Pass”). A result of deploying the command-executing duration corresponding to each command subsequent to each decay command may be as shown FIG. 7. In FIG. 7, a parameter of “Delay” in each of the rows No. 6, 8, 9 and 10 is adjusted again.

In step S13, the SETWP test is again to acquire test data, and it is determined whether the CPU meets a requirement according to the test data.

The test data includes a temporal difference between a moment at which an earliest rising edge appears in a generated cso signal and a moment at which each falling edge appears in a generated alert signal.

In a specific embodiment, reference is made to FIG. 8, which is a graph of curves that are finally generated. There are three falling edges in the alert signal, and each of the three falling edges corresponds to a command of row No. 8, 9, or 10. Appearance of the falling edge means a corresponding command being executed. At such time, a curve of a voltage signal corresponding to such command is subject to a falling edge.

The temporal difference between the moment at which the earliest rising edge appears in the cso signal and the moment at which each falling edge appears in the generated alert signal is calculated. Thereby, a technician is capable to analyze whether a CPU is normal according to the calculated temporal difference.

The curve at a bottom part of FIG. 6 and FIG. 8 is a curve of a voltage signal corresponding to a command of row No. 8, 9, or 10.

In these embodiments, the decay command in the SETWP test and the command-executing duration corresponding to each command subsequent to the decay command can be automatically deployed. Thereby, the SETWP test is correctly performed for the CPU to obtain a test result. It is not necessary to rely on manual adjustment on a parameter of a delay corresponding to each command.

In addition, these embodiments provide a clear concept and a clear method for debugging to testing personnel. An issue of script errors is addressed, avoiding a waste of time due to random manual modification. Thereby, a success rate of debugging is increased with conciseness and high efficiency.

Reference is made to FIG. 9. In an optional embodiment based on any above embodiment, the step S12 may include steps S31 to S35.

In step S31, a falling edge which is i^(th) earliest in the generated alert signal is acquired, and a command corresponding to the falling edge is determined.

i is a positive integer greater than or equal to 2.

In a specific embodiment, the step S12 starts from i=2. Each command corresponds to a voltage signal. A waveform of each voltage signal may be detected by a probe. When the i^(th) earliest falling edge appears in the alert signal, a falling edge would appear in the waveform of the voltage signal as well. Then, the command corresponding to the voltage signal is determined, that is, the command corresponding to the i^(th) earliest falling edge is determined.

In step S32, it is determined whether the command is i-1^(th) in location among all commands subsequent to the decay command.

The process goes to step S33 in case of positive determination. The process goes to step S34 in case of negative determination.

In a specific embodiment, since the command-executing duration corresponding to each command subsequent to the decay command needs to be adjusted in turn, the command i-1^(th) in location subsequent to the decay command is to be adjusted at present. In a case that i equal 2, it is the very next command after the decay command that is to be adjusted.

There is a possibility that the commands subsequent to the decay command are not executed in order. For example, the command 2^(nd) in location subsequent to the decay command is executed before the one 1^(st) in location subsequent to the decay command. Thus, there is a process of determining whether the command is the command i-1^(th) in location among all commands subsequent to the decay command. In case of negative determination, an order of the commands needs to be adjusted.

In step S33, a second command-executing duration corresponding to the command, which is i-1^(th) in location among all commands subsequent to the decay command, is determined and deployed.

In an optional embodiment based on this embodiment, the step S33 may include following steps 1) to 3).

In step 1), a third moment at which the earliest rising edge appears in the generated cso signal and a fourth moment at which the i-1^(th) earliest falling edge appears in the generated alert signal are acquired.

In step 2), a second temporal difference between the third moment and the fourth moment is calculated.

In step 3), the second command-executing duration is calculated and deployed, according to the second temporal difference.

In a specific embodiment, the step S33 is implemented in a manner similar to steps S21 to S23. Reference is made to corresponding forgoing description, which is not repeated herein.

In step S34, the command and another command that is i-1^(th) in location among all commands subsequent to the decay command are swapped.

In a specific embodiment, the command and the i-1^(th) command are swapped. That is, the command and the i-1^(th) command exchanges locations. Hence, the command may be prior in execution.

The process goes to the step S33 after the step S34.

In step S35, it is determined whether the command now i-1^(th) in location is a final command that needs to be executed in the SETWP test.

The process terminates, in case of positive determination. The process returns to step S31, in case of negative determination. The process terminates until the second command-executing duration is deployed for each command subsequent to the decay command.

An objective of the step S35 is ensuring that the second command-executing duration is deployed for each command subsequent to the decay command.

After the second command-executing duration is deployed for each command subsequent to the decay command, the SETWP test can be normally executed, and the test data is acquired.

Before determining and deploying the first command-executing duration corresponding to the decay command in the SETWP test, a parameter “load” for a load on each voltage signal should be fixed, and the parameter “load” should not change freely during the entire debugging. A reason lies in that the parameter “load” influences a result of executing the script.

In this embodiment, the parameter “load” for each voltage signal is constant, eliminating unnecessary factors that affect execution of the script. A value of “Delay” is calculated based on the temporal difference. It is determined through probe detection whether an execution order of the script needs to be adjusted. Each command is adjusted in turn in the debugging process. Each failed (“Fail”) command in the script is sequentially adjusted to be a passed (“Pass”) command. Eventually, the whole script is successfully debugged.

On a basis of on the above method embodiments, an apparatus for performing a test for a CPU is provided according to another embodiment of the present disclosure. Reference is made to FIG. 10. The apparatus may include a first deploying module 101, a second deploying module 102, and a data acquiring module 103.

The first deploying module 101 is configured to execute a SETWP test for a CPU, determine a first command-executing duration corresponding to a decay command in the SETWP test, and deploy the first command-executing duration.

The second deploying module 102 is configured to execute the SETWP test again, and adjust a command-executing duration corresponding to each command subsequent to the decay command in the SETWP test.

The data acquiring module 103 is configured to execute the SETWP test again to acquire test data, and determine whether the CPU meets a requirement according to the test data.

The test data includes a temporal difference between a moment at which an earliest rising edge appears in a generated cso signal and a moment at which each falling edge appears in a generated alert signal.

In an embodiment, the first deploying module 101 may include a first acquiring sub-module, a first calculating sub-module, and a second calculating sub-module.

The first acquiring sub-module is configured to acquire a first moment at which the earliest rising edge appears in the generated cso signal and a second moment at which an earliest falling edge appears in the generated alert signal.

The first calculating sub-module is configured to calculate a first temporal difference between the first moment and the second moment.

The second calculating sub-module is configured to calculate the first command-executing duration according to the first temporal difference.

In one embodiment, when calculating the first command-executing duration according to the first temporal difference, the second calculating sub-module is specifically configured to calculate a ratio of the first temporal difference to a preset value, and determine the ratio as the first command-executing duration.

In these embodiments, the decay command in the SETWP test and the command-executing duration corresponding to each command subsequent to the decay command can be automatically deployed. Thereby, the SETWP test is correctly performed for the CPU to obtain a test result. It is not necessary to rely on manual adjustment on a parameter of a delay corresponding to each command.

In addition, these embodiments provide a clear concept and a clear method for debugging to testing personnel. An issue of script errors is addressed, avoiding a waste of time due to random manual modification. Thereby, a success rate of debugging is increased with conciseness and high efficiency.

The swapping sub-module is configured to swap the command and another command that is i-1^(th) in location among all commands subsequent to the decay command, in a case that the first determining sub-module determines that the command is not i-1^(th) in location among all commands subsequent to the decay command.

After the swapping sub-module swaps the command and the i-1^(th) command, the deploying sub-module is configured to determine the second command-executing duration corresponding to the command, which is now i-1^(th) in location among all commands subsequent to the decay command, and deploy the second command-executing duration.

The second determining sub-module is configured to determine whether the command is a final command that needs to be executed in the SETWP test.

In a case that the second determining sub-module determines that command is not the final command, the second determining sub-module is further configured to acquire a falling edge i^(th) earliest in the generated alert signal and acquire a command corresponding to the falling edge, unless the second command-executing duration corresponding to each command subsequent to the decay command is deployed.

A value of “Delay” is calculated based on the temporal difference. It is determined through probe detection whether an execution order of the script needs to be adjusted. Each command is adjusted in turn in the debugging process. Each failed (“Fail”) command in the script is sequentially adjusted to be a passed (“Pass”) command. Eventually, the whole script is successfully debugged.
